caption_attribution_description: English: The Queen Mother Reservoir There is a sailing club based at the reservoir. The club house is at the top of the bank at reservoir level. It was too choppy to go out today.
context_page_description: The Queen Mother Reservoir is a public water supply reservoir that lies between the M4 and the M25 to the west of London. It is 475 acres in size or about 1 km in diameter - making it one of the largest inland areas of water in Southern England. It is managed by Thames Water.
  This is one of a number of reservoirs to the west of London and was completed in 1976. It was inaugurated on 9 July that year by Queen Elizabeth The Queen Mother, after whom it is named. Its water is pumped from the River Thames nearby. The water improves in quality during its retention in the reservoir as solids settle and organic contaminants are adsorbed and degraded through a combination of natural biological processes aided by sunlight and oxygenation. Water from the reservoir is treated before being put into supply as London tap water. The reservoir contains a limnological tower.
  During the design and early construction it was called the Datchet reservoir.
  Engineering design data for the Queen Mother reservoir is as follows.
  The reservoir lies within the Colne Valley regional park and like other local reservoirs is popular for sailing and bird-watching. Petrels have been spotted at this reservoir.

The water improves in quality during its retention in the reservoir as solids settle and organic contaminants are adsorbed and degraded through a combination of natural biological processes aided by sunlight and oxygenation. Water from the reservoir is treated (often using slow sand filters) before being put into supply as London tap water.  The reservoir contains a limnological tower.
